About Grey Heron Zen Meditation Dublin

The word ‘zen’ means meditation. To ask which religion it belongs to is like asking which country water comes from.  It belongs everywhere.  So why bother at all with Zen if meditation is part of every tradition?  The reason is that Zen is utterly clear and rigorous and practical about meditation, providing a structure that at once supports and challenges one’s efforts. People who practise Zen are not taking leave of their faith, but attempting to deepen it by using the sharpness and precision of Zen practice to cut through egocentric habits of thought that prevent entry into depth.

To allow everything ‘to be and to mean itself’ is to enter into depth, to contemplate.  This is not a journey – ‘passing from one thing to another’ – but rather a cessation of movement.  Meister Eckhart, the 14th-century Dominican,  described his ‘way’ as ‘a pathless path’ – a phrase that instantly recalls Zen.  ‘To study the Way is to study the self; to study the self is to forget the self!’ wrote Dogen Zenji, the 13th-century founder of the Soto Zen school. 

Zen without a vibrant community is like a tree without roots. And while it has firm roots in India, China and Japan, this tradition of deep attention is not alien to us here in Ireland. We seek not to just transplant it from its Asian roots, but rather allow it to adapt to and take root in the Irish psyche suffused with the resonances of our rich monastic tradition and deep respect for nature within our Pre-Christian roots.

Where spring rises in the little wood of birch and sycamore beside the house,

I stand and listen to the undying source whispering there.

I’d travel if I could through the lost ages to a distant time when it was sacred, to a pre-Christian God.

I’d tie a token to a thorn, and climb back to the present, sure in the belief we can still touch the origins of life

It is the energy and commitment of the group of practitioners that gathers in Tallaght that has allowed the Sangha to develop and evolve.The Sangha’s energy has taken the group in new and life integrating ways.

In 2019, one of the Sangha, Professor Padraig O’Cearbhaill translated the four vows into Irish and the Evening Gatha. He then brought a sean-nos air to the vows.


The Grey Heron Zen is affiliated through its teacher, Miriam Healy, with The White Plum Asanga founded by Maezumi Roshi of Los Angeles Zen Centre and the Zen Peacemaker Order founded by Roshi Bernie Glassman.
